Google India / Tez — transaction was successful but the beneficiary was not credited.

Address: Bangalore, Karnataka, 560064

On 27/10/18 i transferred 1000 to someone and the transaction was successful but the receiver was not credited. After 3 days i raised a dispute, complained in the feedback section but its been more than 20 days but still haven't received any response or update on the status.
After raising a dispute i only received this message and nothing else afterwards-
